[PATCH 1/3] drm/i915: Mark up GTT sizes as u64

[Timo Aaltonen]

From: Chris Wilson <chris at chris-wilson.co.uk>

BugLink: https://bugs.launchpad.net/bugs/1815172

Since we use a 64b virtual GTT irrespective of the system, we want to
ensure that the GTT computations remains 64b even on 32b systems,
including treatment of huge virtual pages.

No code generation changes on 64b:
